Custom waypoint Static Line Paradrop - AI will fly towards waypoint position and any units in cargo will jump out of a perfectly good airplane with static line parachutes. Parachute backpacks are not required, the parachute spawns independent of it.~ Keep the Pilot/s in their own group from the paratroopers. Multiple planes can be in the same group but it's better if you don't do that. Similarly put a move waypoint in the same direction as the paradrop waypoint if you want them to keep flying straight
